Intended Use

The Sight Sciences Viscoelastic Injector is a manually operated device for delivery of small amounts of viscoelastic fluid, for example Healon™ or HealonGV™ from Abbott Medical Optics (AMO), Amvisc™ from Bausch & Lomb, or PROVISC™ from Alcon, during ophthalmic surgery.

Device Story

Sterile, single-use, manually operated handheld instrument; used by ophthalmologists during ophthalmic surgery. Device functions as volume-exchange pump; similar to syringe. User loads viscoelastic fluid into internal polycarbonate reservoir; rotates finger wheels on handle to advance stainless steel plunger tube; injection tube (polyimide) dispenses fluid through stainless steel cannula. Finger wheels allow ambidextrous operation for left or right eye. Device provides controlled delivery of viscoelastic fluids (e.g., Healon, Amvisc, PROVISC) to eye. Benefits include precise, controlled fluid administration during surgical procedures.

Clinical Evidence

Bench testing only. Evaluated device integrity, viscoelastic solution delivery, simulated use, and dimensional/visual inspections. Acceptance criteria based on predicate dispensing performance and material strength.

Technological Characteristics

Materials: Polycarbonate (reservoir), stainless steel (plunger tube, cannula), polyimide (injection tube). Passive, manually operated, handheld device. Single-use, sterile. Syringe-based volume exchange dispensing mechanism. Ambidextrous ergonomic design with distal finger wheels.

Indications for Use

Indicated for delivery of small amounts of viscoelastic fluid during ophthalmic surgery in patients requiring such procedures.

Regulatory Classification

Identification

An infusion pump is a device used in a health care facility to pump fluids into a patient in a controlled manner. The device may use a piston pump, a roller pump, or a peristaltic pump and may be powered electrically or mechanically. The device may also operate using a constant force to propel the fluid through a narrow tube which determines the flow rate. The device may include means to detect a fault condition, such as air in, or blockage of, the infusion line and to activate an alarm.

#### 4.1 DEVICE DESCRIPTION

The Sight Sciences Viscoelastic Injector is a sterile, single use, manually operated instrument used by ophthalmologists to deliver small amounts of viscoelastic into the eye during ophthalmic surgery. The Viscoelastic Injector is designed to function with commonly used viscoelastic fluids made commercially available by companies such as Abbott Medical Optics (AMO), Bausch & Lomb, and Alcon. The Sight Sciences Viscoelastic Injector dispenses fluid on the principle of exchanging volumes much like a syringe. The handheld instrument includes a cannula, injection tube, internal reservoir, plunger tube and finger wheels. The finger wheels on the handle of the device are used to advance the plunger tube into the viscoelastic fluid reservoir thereby dispensing viscoelastic fluid. The finger wheels are placed on both sides of the handle facilitating viscoelastic delivery in either the left or right eye (OD or OS) using either hand.

{1}------------------------------------------------

The Sight Sciences Viscoelastic Injector dispenses fluid on the principle of exchanging volumes much like a syringe. The Viscoelastic Injector components responsible for the fluid dispensing are the following:

- Prior to use, the viscoelastic fluid is loaded into the reservoir (polycarbonate) . contained within the handle.
- The reservoir communicates with the plunger tube (stainless steel) which is . connected to the injection tube (polyimide). During use, the plunger tube displaces volume in the reservoir thereby dispensing fluid.
- . The injection tube is initially located within the cannula (stainless steel), advances and retracts from the device to dispense fluid. The injection tube is analogous to a syringe dispensing-tip.
- . The finger wheels move the injection tube in and out of the cannula tip and drive the plunger tube into the reservoir to dispense viscoelastic fluid in a controlled manner.

#### 4.2 INDICATION FOR USE

The Sight Sciences Viscoclastic Injector is a manually operated device for delivery of small amounts of viscoelastic fluid, for example Healon™ or HealonGV™ from Abbott Medical Optics (AMO), Amvisc™ from Bausch & Lomb, or PROVISC™ from Alcon, during ophthalmic surgery.

## 4.3 TECHNOLOGICAL CHARACTERISTICS COMPARISON

The intended use and technical features of the Sight Sciences Viscoelastic Injector are substantially equivalent to the Viscolnjector (K050716) marketed by iScience Surgical. Both devices are manually operated for controlled delivery of small amounts of viscoelastic fluid. Fluid is dispensed from each system on the principle of exchanging volumes much like a syringe. Table 1 compares the attributes of the iScience Viscolnjector with the Sight Sciences Viscoelastic Injector.

### 4.4 BRIEF SUMMARY OF PERFORMANCE TEST RESULTS

The device's descriptive characteristics are well-defined and adequate to ensure equivalence of the Sight Sciences Viscoelastic Injector. Additionally, performance testing was designed and conducted to evaluate device integrity, delivery of viscoelastic solutions, simulated use testing, and dimensional and visual inspections. Acceptance criteria was based on viscoinjector dispensing performances, intrinsic strength of the materials, and the load to which the Sight Science Viscoelastic Injector would be subjected during intended use.

Testing demonstrated that the proposed device performs as intended and is functionally equivalent to the predicate device.

#### ને રે CONCLUSION

The Viscoelastic Injector by Sight Sciences, Inc. meets all product design requirements and applicable standards and embodies technological characteristics similar to the predicate devices, the device has been shown to be substantially equivalent to the predicate devices, and is safe and effective.
